In Party cookie - GA a virtual first party i saw for my self that GA do use first-party cookies. In this post I'll have a quick look at the javascript that does this, which is loaded from http://www.google-analytics.com/urchin.js and started by a call to urchinTracker();.
The JavaScript file consists basically of three sections
- Variable declarations that can be customized
- Variable declarations that can't be customized
- Function definitions
where the function definition takes up approximately 90% of the LOCs. I'll happily restate that I'm no expert on JavaScript, in fact I avoid it if possible and therefore have read og even written much of it. I guess the code in the file has been optimized for minimum size (and probably also performance), and therefore variable declarations and functions do not use meaningful names, so it looks a lot like old school C (as old as my schooling goes), which makes it harder to read and understand. A quick look at the function prototypes (done with
grep function urchin.js | grep -v -E "linker|typeof|onload" | sort | cut -f1-2 -d' ') gives
28 functions, that sorted goes as:
Not much help here, so there's only the (uncommented) code left. Here I've pretty printed it using the online tool http://elfz.laacz.lv/beautify/, which does a descent job, except for moving end of line comments to the next line (watch out for that in the start). I've looked for a JavaScript editor for Eclipse, that would give me pretty printing but I haven't found one yet, which surprises me since there must be a lot of people doing javascript, but it must be in other tools. Here comes the all most 1000 lines long pretty printed version:
